Peter Cullen (Optimus) and Gregg Berger (Grimlock) are joined by Nathan Drake himself, Nolan North as the Fall of Cybertron cast gets fleshed out.

The voice cast, which includes Ultimate Spider-Man and Avengers: Earth's Mightiest Heroes voice actor Fred Tatasciore (Megatron, Ratchet, Metroplex) along with Guinness Record holder for most video game voice roles, Steve Blum (Shockwave, Swindle, Sharpshot), looks to have been filled out quite nicely with a selection of veteran voice actors. The only downside: Frank Welker, voice of the original Megatron and currently handling the character on the franchise's latest animated incarnation, Transformers: Prime, is nowhere to be seen (or heard, I guess).

The announcement promises that more names are on the way, but in addition to North as Bruticus, Cliffjumper, and Brawl, we've got Troy Baker as Jazz, Jetfire, and Kickback, as well as Isaac Singleton as Soundwave.

Transformers: Fall of Cybertron will be available on August 28th for the Xbox 360 and PS3.
